The north of the house faces a road.

How far is the house from the road? If it is too close, it is easy to form a road surge.

Although Luchong is evil, it is not necessarily in your home or next door. This depends on the quality of the house. Moreover, it also depends on the strength of the road rush. If the road extends far and there are no buildings at the far end of the road, then it is very powerful. If there are no windows in the north of your house, it's not a big problem.
